Picked up my 2017 Tri Glide today only had time to put 100 miles on it,so here are my initial thoughts.First the ride seems just a wee bit better in the front same in the rear,brakes are the same as my 16 Tri. No oil pressure reading on the Info center it just says OK,overall engine noise is a little better than the 16.Now for the important items,Trans shifts a lot better without that loud clang it still makes noise but nothing like the 16.Heat management is a whole lot better it was in the mid 80's today and i never felt the roasted leg syndrome.The engine seems no smoother than the 16. But with all that the power this engine makes is amazing. My 16 had slipons with a gutted pipe,SE air cleaner and backing plate with a Fuel Moto download and the new 107 is hands down more powerful.The gearing seems different because we can cruise along at 45-50 in 5th gear and just roll on the throttle and this thing pulls,plus my 16 had a lot of backlash when rolling off the throttle you could hear it clunk,not the 17 very quite,so I am very happy at this point that I upgraded.Only time will tell as far as reliability goes.
